The Juárez Cartel controlled one of the primary transportation routes for billions of dollars worth of illegal drug shipments annually entering the United States from Mexico. They were a ruthless and dangerous drug trafficking organization that had been known to decapitate their rivals, mutilate their corpses, and dump them in public in order to instill fear not only in the general public, but also in local law enforcement and their rivals. Juárez Cartel is by far the most powerful criminal organization in Breaking Bad universe.
